Pairwise PERMANOVA results comparing bacterial community composition in the L- and T-compartment of apple saplings at different timepoints (TP) of three differently treated groups (IU, IT, NC). R²-values are illustrated using a color scale with the Benjamini–Hochberg adjusted p-values indicated by asterisks, i.e., “*” represents p ≤ 0.01 and “.” represents 0.05 ≥ p > 0.01. Results for the L-compartment are shown in the upper right side of the figure and for the T-compartment in lower left side. The significance threshold was set at α = 0.01
